The Disability Continuum
Although there is no universally accepted meaning for the word “disability”. However, the British Columbia Human Rights Code (RSBC 1996) Chapter 210 provides definitions of disability that form our guiding principles. Definitions of disability can be placed on a continuum. At one end, disability is explained in terms of medical conditions (medical model). At the opposite end, disability is explained in terms of the social and physical contexts in which it occurs (environmental model).
The medical model focuses on deficiencies, symptoms and treatments. The World Health Organization’s (WHO) 1976 definition for disability, for example, is “any restriction or lack (resulting from an impairment) of ability to perform an activity in the manner or within the range considered normal for a human being.” Medical model definitions promote the idea that disability is a deviation from the norm.
Many people with disabilities are troubled by definitions that regard disability as abnormal, preferring instead to portray disability as commonplace, natural, and in fact, inevitable. As people age, they experience gradual declines in visual acuity, auditory sensitivity, range of motion, bodily strength, and mental powers. Significant functional limitations affect almost half of people between the ages of 55 and 79, and over 70% of people over 80 (World Health Organization (WHO) report titled “Ageing and health”, 2015). Beyond middle age, disability is the norm.
The environmental model explains disability in relation to social and physical contexts. In this view, the environment, not an individual’s medical condition, causes disability. For example, during an electrical blackout, a person who is completely blind can effortlessly navigate around the home, hammer nails, and, if a Braille user, read a novel.
A sighted person would be unable to perform these tasks easily, if at all. In this example, the environment disables the sighted person.
The environmental model emphasizes that people with disabilities are capable individuals, and it is the barriers in the built and human environments, not their medical conditions, that create disability. Disability occurs when the world is designed only for a certain way of living, without considering the natural variation among human beings. Barriers are created by humans, and modifying how we live, the tools we use, and our understanding of the proper way to do things can eliminate or minimize design problems that cause barriers. Systematic barriers can be eliminated by modifying policies, plans, and processes. Attitudes that cause barriers can be addressed through disability awareness, respect, and positive interactions with people with disabilities.
Types of Disability and Functional Limitations
A person’s disability may make it physically or cognitively challenging to perform everyday tasks such as operating a keyboard, reading a sign, differentiating colours, distinguishing sounds, climbing stairs, grasping small items, remembering words, or doing arithmetic.
There are many kinds of disabilities, including physical, sensory, hearing, mental health, developmental and learning. Disabilities can be visible or invisible.
Visual Disabilities
Visual disabilities reduce one’s ability to see clearly. Very few people are totally blind. Some have limited vision such as tunnel vision, where a person has a loss of peripheral or side vision, or a lack of central vision, which means they cannot see straight ahead. Some can see the outline of objects while others can see the direction of light. Impaired vision can restrict a person’s ability to read signs, locate landmarks or see hazards. In some cases, it may be difficult to tell if a person has a visual disability. Others may use a guide dog or white cane.
Here are some suggestions to help you interact with people with visual disabilities:

Hard of Hearing and Deafness
People who have hearing loss may be deaf or hard of hearing. Like other disabilities, hearing loss has a wide variety of degrees.

Some people who have severe difficulties may use communication boards, sign language or other assistive devices.

Deaf-Blind Disabilities
A person who is deafblind cannot see or hear to some extent. This results in greater difficulties in accessing information and managing daily activities. Most people who are deafblind will be accompanied by an intervener, a professional who helps with communicating. Interveners are trained in special sign language that involves touching the hands of the client in a two-hand, manual alphabet or finger spelling, and may guide and interpret for their client.
